Charged graphene gives DNA a stage to perform molecular gymnastics

October 14, 2014 9:50 am | by EurekAlert! | Comments

When Illinois researchers set out to investigate a method to control how DNA moves through a tiny sequencing device, they did not know they were about to witness a display of molecular gymnastics. Fast, accurate and affordable DNA sequencing is the first step....

Optimizing renewable energy costs

October 14, 2014 9:46 am | by EurekAlert! | Comments

Increasing reliance on renewable energies is the way to achieve greater CO2 emission sustainability and energy independence. As such energies are yet only available intermittently and energy cannot be stored easily, most countries aim to combine....

Augmented reality melds work, play

October 14, 2014 9:34 am | by SALIM ESSAID, Associated Press Writer | Comments

Mark Skwarek is surrounded by infiltrating militants in New York's Central Park. He shoots one, then hearing a noise from behind, spins to take down another. All of a sudden, everything flashes red. He realizes he's been hit. The words "Game Over" appear....

How the new HealthCare.gov stacks up with the old

October 14, 2014 9:31 am | by RICARDO ALONSO-ZALDIVAR and CALVIN WOODWARD, Associated Press | Comments

HealthCare.gov, the website for health insurance under President Barack Obama's health care law, has been revamped as its second enrollment season approaches. But things are still complicated, since other major provisions of the Affordable Care Act ...

Sensor enables a better fit for prostheses

October 14, 2014 8:33 am | by Sandia National Laboratories | Comments

As an amputee walks on a prosthetic leg during the day, the natural fluid in the leg shifts and the muscles shrink slightly. Now imagine the problem that poses for the fit of the prosthesis. There’s a growing need for a solution. The national ...

Graphene acts as a fine lubricant

October 13, 2014 6:30 pm | by Argonne National Laboratory | Comments

Nanoscientist Anirudha Sumant and his colleagues at Argonne’s Center for Nanoscale Materials and Argonne’s Energy Systems division applied a one-atom-thick layer of graphene, a two-dimensional form of carbon, in between a steel ball and a steel disk....

Review: Music player learns your tastes over time

October 13, 2014 2:33 pm | by BARBARA ORTUTAY, AP Technology Writer | Comments

Some things get better with time: wine, jeans and this "smart" music player I've been using on and off for a few months. The idea behind the $399 Aether Cone is that over time, it learns your listening habits and weighs such factors as whether it's a lazy Sunday morning....

Getting sharp images from dull detectors

October 13, 2014 2:14 pm | by EurekAlert! | Comments

Observing the quantum behavior of light is a big part of Alan Migdall's research at the Joint Quantum Institute. Many of his experiments depend on observing light in the form of photons — the particle complement of light waves — and sometimes only one....

A novel platform for future spintronic technologies

October 13, 2014 2:09 pm | by EurekAlert! | Comments

Spintronics is an emerging field of technology where devices work by manipulating the spin of electrons rather than their charge. The field can bring significant advantages to computer technology, combining higher speeds with lower energy consumption....
